The primary contributor to the stack # usage seems to be openvswitch, which is used by OVN-Kubernetes (based on # OVN (Open Virtual Network)), but NFS also contributes in some stack # traces. # # There may be some opportunities to reduce stack usage in the openvswitch # code, but doing so potentially require tradeoffs vs performance, and # also requires testing across architectures. # # Looking at stack usage across the kernel (using -fstack-usage), shows # that ppc64le stack frames are on average 50-100% larger than the # equivalent function built for x86-64. Which is not surprising given the # minimum stack frame size is 32 bytes on ppc64le vs 16 bytes on x86-64. # # So increase the default stack size to 32KB for the modern 64-bit Book3S # platforms, ie. pseries (virtualised) and powernv (bare metal). That # leaves the older systems like G5s, and the AmigaOne (pasemi) with a 16KB # stack which should be sufficient on those machines. # # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Signed-off-by: Aneesh Kumar K.V (IBM) <aneesh.kumar@kernel.org> # Link: https://msgid.link/20231215124449.317597-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 18f14afe281648e31ed35c9ad2fcb724c4838ad9 # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig Using /kisskb/src/arch/powerpc/configs/mpc85xx_base.config as base Merging /kisskb/src/arch/powerpc/configs/85xx-32bit.config Merging /kisskb/src/arch/powerpc/configs/85xx-hw.config Merging /kisskb/src/arch/powerpc/configs/fsl-emb-nonhw.config # # merged configuration written to .config (needs make) # # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4579:warning: override: reassigning to symbol PPC_E500MC .config:4580:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/build_bug.h:5, from /kisskb/src/include/linux/container_of.h:5, from /kisskb/src/include/linux/list.h:5, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:15: /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c: In function 'allocate_bd': /kisskb/src/include/linux/err.h:28:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 28 \| #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) \| ^ /kisskb/src/include/linux/compiler.h:77:45: note: in definition of macro 'unlikely' 77 \| # define unlikely(x) __builtin_expect(!!(x), 0) \| ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:138:13: note: in expansion of macro 'IS_ERR_VALUE' 138 \| if (IS_ERR_VALUE(fep->ring_mem_addr)) \| ^~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc85xx_defconfig+KVM_powerpc-gcc13 # Build took: 0:01:48.447071
